Airwire/Ratsnest problem with jumper

autodeskguest

I don't have very much experience with Eagle so I think there may be a

simple solution for this. It is a project for school. If you open the

picture attached you can see that after adding a jumper, that airwire

seems to have forgotten where it belongs.

    This worked perfectly on at least 5 other jumpers but not this one. How

    do I get the jumper to be part of the net? Whats the right way to add a

    jumper?

     

    It may not be the way you added the jumper.  It might be the way you

    added traces.  It seems the only way to get Eagle to recognize a trace

    as part of a net is to add it using the "Route" funciton.  If you add

    a trace using the "Add Trace" funciton, Eagle does not count it when

    computing where to put airwires.  You can tell if the trace was added

    correctly by trying ot delete it (using Delete, not Rip-up).  If you

    try to delete a trace that was added with Route, then Eagle will not

    let you do it.  It will say you can't do this in the board.  Do it in

    the schematic instead.  But if Eagle lets you delete a trace without

    complaint, either you are not editing with a consistent schematic, or

    the trace was put there some way other than with the Route function.
